Thread: Barrel threading for suppressor

I am going to buy an ASE SL5i suppressor for my Tikka 260, I'm thinking of going for a M14x1 thread.
Am I right in thinking that you require a 1mm shoulder for the suppressor the tighten against?
My Tikka muzzle has a diameter of 15.6mm so an M15x1 would be a little too big?

Also, can anyone recommend somewhere in the Waikato or Auckland where I can get my barrel threaded?
Don't want someone that is going to stuff up my rifle, but some places seem to charge up to $130 which seems pretty steep.

Cheers

Probably telling you something you already know, but DPT will do it for $95. http://dpt.co.nz/product.php?id_product=62

Depends on the manufacturer specs. At dpt yes, it is 1 mm.

What Stretch said. Just had one done by dpt last week. First class job and turnaround was less than a day.

Cheers, think i'll look into DPT.
Did they re-crown your barrel? I see they say they do this when threading and not sure what the reason is?

IF they take any length off, then recrowning is required. If they're only threading without shortening, then decrowning probably not necessary. But then, I'm not a gunsmith.

We re-crown all barrels we thread.
The live center sits against the crown while thread so that could cause damage to the existing crown, so a re-crown takes care of that.

Do all the other suppressor fitters do this? Yours is the only website that says you do, or do they use other methods of threading?

I have no idea. What are your worries on having your crown redone?

Not necessarily worried, more just interested into whether other places do it or not.
I suppose there is risk of stuffing it up and accuracy goes to shit, not that I'm suggesting you would stuff it up.
In some ways could improve accuracy if the rifle had a sub-par crown from factory.

I think gunworks may do it the same way but apart from them I have no idea.
We do thousands of rifles this way each year, so I wouldn't worry too much about it if I was you.

not a comment regarding crowning, but I have a number of rifles with suppressors and all except one I had the threading done by the company who supplied the suppressor (DPTx2, Hardyx1) and the only one I did differently was had a threading done by an unknown gunsmith via the gun shop I bought the 17HMR from. Cheaper and less hassle (so I thought). Ordered a can from Gunworks. The alignment must be slightly off as the first couple of rounds clipped the edge of the suppressor exit hole. Imagine if I had that issue with a high powered centrefire! From that experience alone I would urge you to get the suppressor supplier to do it

Hi,

We recommend atleast 1.5 mm, so 15.6 mm is right about at the lower limit for M14x1 threads.

Please see our threading specs here for the most common metric threads we sell:
